Abstract: We present a compilation of tropospheric (CO2)-C-14 for the period 1950-2010, based on published radiocarbon data from selected records of atmospheric CO2 sampling and tree-ring series. This compilation is a new version of the compilation by Hua and Barbetti (2004) and consists of yearly summer data sets for zonal, hemispheric, and global levels of atmospheric C-14. In addition, compiled (and extended) monthly data sets for 5 atmospheric zones (3 in the Northern Hemisphere and 2 in the Southern Hemisphere) are reported. The annual data sets are for use in regional and global carbon model calculations, while the extended monthly data sets serve as calibration curves for C-14 dating of recent, short-lived terrestrial organic materials. © 2013, Arizona Board of Regents on behalf of the University of Arizona
